WIRE LATHING.

Specification of Letters Patent. Patented Feb, 14, 1922 Application filed June 28, 1918. Serial No. 242,368..

To all whom it may concern.

Be it known that I, GEORGE M. WRIGHT, a

citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in a W ire Lathing, of which the following, taken' in connection with the accompanying drawing, is a specification.

-My present invention relates to improvements in lathing composed of a wire fabric adapted to be covered with plaster which is securely held between the meshesof the fabric. The objects of my invention are to stlfien the woven wire fabric, and to provide means for drawing the fabric taut over the surfaces to which it is applied, and to hold the wire fabric at a uniform distance from the furring or the structural beams of the building. These objects, among others, I accomplish by the construction hereinafter described and illustrated in the accompanying drawings, the novel features being pointed out in the annexed claims.

Referring to the drawings,

Figure 1 is an elevation of asection of wire lathing as applied in position toreceive a coating of plaster.

Figure 2 is an edge View of a section of wire lathing, shown in sectional view.

Figures 3 and 4 illustrate details of construction showing the application of the sheet metal stiffening strips'to the tension rods or wires.

Similar reference characters refer to similar parts in the different figures.

The wire lathing to which my invention relates is composed of interwoven warp and weft strands of wire forming rectangular meshes of about three eighths of an inch square, as represented in Fig. 1, which shows a small section detached from a larger sheet, but sufiicient in size to illustrate the character of my present invention. Upon the rear side of the lathing, or the side which is to lie next the wall of the building, I place metal strips, preferably of sheet steel, transversely to -the woven fabric, as represented in Figs. 1 and 2, in which 1 denotes the warp strands, and 2 the weft strands of the woven fabric. 3 represents the transverse strips of sheet metal which are V-shaped in cross section when applied to the woven fabric. Between the edges and the apex of the strips 3 I place wires 4 r lengthwise of the woven fabric, which I term tension rods, as they are employed to receive the strain necessary to draw the woven fabric taut over the surface to which it is to be applied.

In the construction of my improved wire lathing, I first string the sheet metal strips 3 upon the tension rods, said strips having holes therethrough to receive the tension rods. The strips 3 when strung upon the tension rods 4 are U-shaped in cross section, as represented at 5, Fig. 3, and have their edgesfi turned upwardly toward the tension rods '4. The strips are then spread apart forming a V-shape, as represented at. 7 Fig.

4, until theirv edges 6 are brought into contact with the tension rods. The holes 8, 8, Figs. 3 and 4, are large enough to freely receive the tension rods and allow the stiffening strips 3 to be properly spaced thereon. When the strips are spread apart, as shown in Fig. 4, the holes 8, 8, are caused to bite the tension rods 4 sufficiently to hold the stifiening strips from slipping on; the ten sion rods. When the strips 3 have been applied to the tension rods 4, as described, the wire fabric forming the body of the lathing is placed against the turned up edges of the strips 3, as represented in Fig. 2, and a clip 9 is carried around the apex of the stiffening strips 3, with the ends 10 of the clip bent over two adjacent weft wires 2, thereby securely attaching the stiffening strips 3 to the woven fabric.

In applying the woven fabric to the surface to be covered thereby, I lace eyebolts 11, if the application is to a cei ing, to which I attach tension rods 4 which are drawn taut byiany suitable means, such for example, as by the use of a fence stretching device, and the opposite ends of the tension rods are then securely attached to similar eyebolts, thereby drawing the woven fabrlo taut over the surface to be covered, with the clips 9 resting against'the structural beams of the building, represented by the broken lines 12, Fig. 2, or against fur-ring, if such is used. By this application of the lathing a uniform space is maintained between the woven fabric and the furring, to enable the plastering to be crowded through the meshes of the lathing in sufficient amount to securely fasten it to the lathing. if lathing is to be applied to the vertical walls of the building, pins may be substituted for the eyebolts 11..

I claim,

1. A Wire lathing comprising a meshed fabric, V-shaped transverse stiffening strips, tension rods or Wires passing through holes in said stiffening strips, with the edges of said stiffening strips turned over and bearing against said tension rods, clips attaching said strips to the fabric, and means for supporting said rods under tension.

2. A Wire lathing comprising a meshed fabric, V-shaped transverse stiffening strips, tension rods passing through holes in said strips, with the edges of said strips turned over in contact with said tension rods, and means for attaching said stiffening strips to the back side of said fabric.

3. In a Wire lathing, the combination of a WOVQII Wire fabric, angular stiffening strips on the back side of said fabric and transversely thereto, tension rods passing through said strips, and means foriattaching said stiffening strips to the Woven fabric, consisting of metal clips extending around said stiffening strips adjacent to said tension rods, with their ends bent over and inclosing the Wires of the Woven fabric, whereby the latter is united to said stiffening strips. Dated this 17th day of June, 1918.
